Most notably, ProCharged engines give a very predictable throttle response. Being driven off the crankshaft, no spooling is required which with turbos causes lag. They have a very different torque curve than a twin-screw design and have no internal bypass. Our Whipple builds will, for example, provide explosive, tire-shredding, low-end torque. Our ProCharged builds will come on softer,…

If you can get the power you want out of your engine naturally aspirated, that's probably the way to go. The OEs need superchargers to get into the 700 hp territory. We don't. This pump gas LS engine puts out 800 hp all on its own. This build features a Dart LS Next SHP iron block with a 4.125 inch bore.
